So i have a problem and im hoping to get advice on whos right and whos wrong so bare with me here;

So about 5 weeks ago i buy my new R53 2005 89k miles. Few minor issues so i decide to get to work. I bring it to my mechanic who i always use to get an oil and filter changed. He does that about a week later theres a nasty grinding/ rattle coming from the engine when i start it, this continues to happen until i rev it to 2k rpm in which case it goes away (I assume after oil pressure builds a bit) . Hes out of town and i bring it to a specialist near where i live. They said its the timing tensioner. Great, Problem solved so i decide to get him to do the job and one or two other things which include an oil and filter change (again) not more than 5 weeks after getting it done by my usual mechanic.

I get a call after dropping off the car and the specialist says that my timing chain is bust. I need a new chain tensioner and guide rails. He said it needs to be done so reluctantly i opt to get it done for the sake of my cars health. When i go to pick it up he shows me the filter which my original mechanic installed. It had been forced in according to the specialist and the wrong way around also. He said this is what causedthe timing chain rattling and about to go too.

So heres where i currently stand. My original mechanic is saying the specialist is lying and that the oil pressure light would have came on if that were the case. Also it would have done alot of internal damage too? He also said the minis are like opel cars where the filter twists from time to time when installed and that the rattle was only caused by the tensioner in which case should only have been replaced.

apologies if ive left out major details but if you have any questions or answers that could shed light on the situation please send on ASAP. I need to get an answer if i was ripped off by the specialist or my original mechanic is covering his ass after screwing it up!
Thanks!

Well there's NO way you broke your timing chain as that's the end of the engine completely. So that's bullshit. Ask for the original parts so you can see them and WHY if the oil filter was in wrong they didn't show you ?
It's going to be hard to prove anything sadly.

Tensioners and guide rails are one the "things that go wrong quite often" list, it's a long list!

A bust tensioner wouldn't bring on low oil pressure light, a blocked filter would.

Did the rattle sometimes go away without revving above 2k? Mine was OK if left for a few hours.

What was the oil like when the specialist changed it? Mine turned black as fuck pretty much a soon as the tensioner went, as the chain slaps about on the casing. There's a video on YouTube which shows the inside of the casing and where it rubs.

Even if the filter was the wrong way round I doubt it would affect the chain before other items, maybe they didn't mean the chain was bust but perhaps the chain guides? If this is the case then I hope they have the sump off to get bits out of the oil pick up and look for other damage. Mechanics do slate each other for want of recognition of being the best in their own opinion, but still aren't psychic, hard to prove anything.

The chain rattle would go away when i revv it for a few seconds at 2k rpm then go away? What issues would the oil filter being put in the wrong way cause?

I can't see how a professional mechanic could fuck up and put it in the wrong way. it sounds more like the new place are trying to justify a plausible job that probably didn't need doing. Did they show you any of the old parts or receipts for the new stuff? I'd be having the rocker cover off to check if the work really has been done

They showed me the oil filter which was badly twisted from what i can only assume is it being forced in. He said he will have a receipt for me tomorrow along with a report. He said he would have it done friday but pushed it to monday so if he changes again tomorrow ill be pretty sceptical. While the rocker covers off might do something cool with it!

I've seen poverty spec oil filters not fit properly before and end up deformed similar to what's being described.
